The matrices are released from the maga- ,the end block 9, the successiveaddition of matrices causing the block 9, together with the base 7 and the extension 16, to move toward the. left in Fig.1. The operation'of the star wheel is such that the. matrices are not'tightly packed against the block 91b11t engage each other loosely, asindicated in Figs. 1 and 2.

The mechanismjust described is that commonalyfound on type casting machines and it-.will be readily understood that, while a scale 12 is provided' on the front plate 10, owing to the loosenessof the matrices on the stick 5 it is impossible to correctly gage from this. scale the number of ems of type corresponding to the matrices.

In order'that the number of ems carried on the stick may be quickly and accurately gagedv I have provided means furnishing a fixedvbase from which an indicator may be calibrated to show exactly the number of ems assembled on the stick. In a suitable supporte36 and secured in any suitable manner to the frame of the machine I mount a clamping member 37 having a tongue 38 adapted to be moved into engagement with the last matrix on the stick and to force all of the matrices against the block 9. The support 36 is provided with a slot 39 through which extends a handle 40 secured to the clamping member 37 "A spring 40 connected to the handle 40' normally holds theclamping member 37in normal retracted position. The tongue 38 moves in an are about the shaftl5 of the star wheel Hand the tongue 38. when in the clamping position is in advance of the arms of the star} wheel a suflicient distance to take up the looseness 0f the matrices and to allow. the star wheel to revolve without'interfering therewith,

On the extension'16 I provide-a raek41 adapted to engage a pinion 42 secured to a shaft suitably mounted in the frame of the machine and a pointer 43 is'secured to the shaft by means of a screw 44, or other suitable means,'and is adapted to move over' a scale 45 on the are 16. The scale45 issuitably calibrated to indicate ems of the particular type face which 'isintended to be used in the gmachine, the zero of the scale being positioned so that the pointer 43 will rest thereon when the block'9] is disposed against 1 the tongue 38 in clamping position; It will be thus seen that for each matrix disposed between the block 9 and the tongue 38 the pointer 43 will move a corresponding distance on'the'scale 45 and hence the number i .65 of ems may be gaged exactly without remov dispensed with and the scale 12 on the plate 10 may be calibrated with reference to the fixed base providedby the tongue 38 of the clamping member 37 or that any other suitable indicating mechanism calibrated with reference theretofmay be substituted.

It is thought that the structure and operation of my device will be clearly understood from' the foregoing withoutfurther description, it being apparent that I have devised a simple and efiective device which maybe readily attached to type casting machines and :which will allow a much more rapid operation of the machine in setting up certain classes of matter, such as tabulations, where it is necessaryto justify the 7 type to properly appear in vertically alined columns. f 7

It will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from, the spirit and scope of the invention or sacrificing any of its material advantages, the form hereinbefore described be ing merely a preferred embodimentthereof.
